Manufacturer's description

Otterley is a rich dual reverb that’s simple to use. It includes two engines: Reverb 1, controlled by just a knob but with a rich and atmospheric flavor, and Reverb 2, a reverse reverb with several associated parameters. Despite its complexity, operation is quite simple, with no menus, no switches and no hidden functions. 

Controls

• Reverb 1: One-knob level and size control for the first engine. As level increases, so do size and modulation complexity for this lush component.
• Reverb 2: Reverse reverb engine blend control, from dry to full wet.
• Feedback: Regeneration for Reverb 2, from zero to almost self oscillation.
• Delay: Time and size for reverse component or Reverb 2, from almost immediate to dry signal to quasi reverse delay character
• Grain: Density for Reverb 2, from identifiable reverb grains to blurred sound strokes at maximum.
• Pitch: Relative pitch for Reverb 2, with unison at centre, two octaves up at maximum and two octaves down at minimum. If used in conjunction with feedback, this can provide spiral up or spiral down effects, as each recirculation will get pitch transposed again.
• Bypass: electronic buffered bypass, with slight decay at off for non abrupt transition.
